我正在尝试编译从http://xmacro.sourceforge.net/下载的 xmacro 。

我正在运行 Fedora 19 LXDE。

问题：我从哪里获得 iostream.h？它不见了。我看到一些包含 iostream.h 的包。软件包版本号 compat-gcc-34-c++.i686 与 g++ (GCC) 4.8.1 20130603 不匹配。应该吗？

我认为下载编译器时会包含 iostream.h。

我已经安装了 gcc-c++、libx11-devel 和 libxtxt。

问题：我得到了正确版本的 c++ 吗？什么是兼容性 GNU 编译器集合？

$ yum search "compat-gcc"
Loaded plugins: langpacks, refresh-packagekit
=========================================== N/S matched: compat-gcc ============================================
compat-gcc-34.i686 : Compatibility GNU Compiler Collection
compat-gcc-34-c++.i686 : C++ support for compatibility compiler
compat-gcc-34-g77.i686 : Fortran 77 support for compatibility compiler

  Name and summary matches only, use "search all" for everything.

我得到：

$ make

iostream.h是后来成为 C++ 标准库的标头的旧的、预标准的名称。现代、标准化的名称只是iostream，没有.h.

最好的解决方案是遍历源并更改iostream.h为iostream无处不在。但是，如果您尝试编译的 C++ 代码确实很古老，您可能会遇到其他问题。另一方面，它可能工作正常，但有一些警告。试一试，看看会发生什么。

如果它不起作用，您可能会发现“compat-g++”包（它具有非常旧的 3.4 版本的 g++）比 4.8 更好地处理这个旧代码。
